  • a trigger operation may be received by a selection of any point on a waveform through an operation using a touch panel.
  • the external trigger reception module 134 generates a trigger at a time corresponding to a measurement value having received a touch operation and saves images before and after the trigger.
  • a trigger is regarded as being generated at a time when a measurement value corresponding to a point A on a waveform is input. In this case, since the trigger is generated backwards, the capacity of the image ring buffer 152 is increased.
  • the time-series measurement value file 191 , the numbered image file 192 , the file management data 193 , and the trigger group management data 194 are archived in one image-attached measurement value file 190 and are saved in the file saving region 160 , but the time-series measurement value file 191 , the numbered image file 192 , the file management data 193 , and the trigger group management data 194 are sufficient if they are associated with each other, and are not necessarily archived in one file. For example, they may be stored in the same folder, or file names that are clearly associated with each other may be attached thereto.
  • the time-series measurement value file 191 , the numbered image file 192 , the file management data 193 , and the trigger group management data 194 may be configured as one file without being archived.
  • the image-attached measurement value file may be divided into four regions, and contents of the time-series measurement value file 191 , the numbered image file 192 , the file management data 193 , and the trigger group management data 194 may be recorded in the respective regions.
  • image data from the plurality of digital communication output cameras 410 may be received.
  • the image data may be associated with measurement data based on a reception time.
  • a measurement function may be added to the digital communication output camera 410 , and measurement data and image data may be received from the digital communication output camera 410 .
